Vitastor 0.5.8 released

2021-03-09

• Add heartbeats (fixes failover in case of network issues or offline nodes)
• Fix a bug where a PG could incorrectly become listed as ‘incomplete’ if historical osd_sets included a set with the the PG’s primary OSD as the only alive one
• Use osd_out_time = 10 minutes by default instead of 30 minutes
• Make monitors stick to a single selected etcd URL on start and not try to select random ones on every request - this was leading to etcd interaction errors when some etcds were unavailable
